If I sent a site link to my friend. With the link, there is an image automatically add. Can I edit or delete this image for my site???

Does the link have an imbedded image in it?

If it does, is the image being hosted on your site. If it is then you can replace the image with what ever image you want as long as the name for the image is the same and it is stored at the same location on your server.

Hi Kanika
I think you are asking about Social Media Graph and Card, when we share the link on social media then Image, Title, and Description embedded to post itself.
So, for that, we are used og tags for Facebook and twitter card for twitter
Example:<meta property="og:title" content="Web Designing Company"/>
